IMPROVEMENT IN HUBS FOR VEHICLE-WHEELS.

Specication forming part of Letters Patent No. 149,625, dated April 14,187,4; application filed December 29, 1873.

To all 'whom t may concern.-

Beit known that I, JOHNSTON V. WOOLSEY, of Sandusky, in the county ofErie and State of Ohio, have invented a certain new and ImprovedCarriage -Wheel Hub, of which the following is a complete description,reference the prevention of the ends of the mortises from giving way orcrowding up by the pressure of the tenon of the spoke while it is beingdriven therein. i For this purpose is used a band, of a peculiar shape,at each end of the mortise', which not only avoids the trouble abovesaid, but which also prevents the hub from'splitting or cracking.

Of the above invention the following is a more complete description Inthe drawings, A represents the hub, which is or may be of the ordinaryWooden kind, having a middle projection, d. B C are bands surroundingthe hub at each end of the mortise-space. It will be seen, onexamination of Fig. 2, that the under inner edge of each band is beveledback under the band, as shown at a, and that the' outer edge of thebands is curved downward, and pressing into the wood, there being agroove made in the hub to receive the edge of the band as it is bent orpressed into it to a little depth, forming a shoulder for the curvededgel of the band to rest against, and thereby prevent it from comingon' or loose. l

. In driving the tenons of the spokes into their inortises, the mortisesat the surface are very liable to crowd out, in consequence of thestrain of the tenon against the ends. This crowding or forcing out ofthe wood weakens the ends of the mortises, so that there is less supportfor the tenon'than if such forcing out of the wood had not been 3 toavoid'which is the purpose of the bands referred to, which are pressedupon the hub at each end of the Inortise ush with the surface. The outeredge then rolled down and pressed into the wood, thereby forming asmooth rounded shoulder, D, while the edge c pressed into the woodprevents the band from coming oi' or loose.

On driving the spoke into the mortise, the ends of the mortise, insteadof being crowded or pushed'out, will be .crowded down under the band, inconsequence of the slant or bevel a on the under side, therebycompressing or packing the wood under the band, and thus making irm andsolid ends to the mortises, for the'support of the tenons of the spokes.

What I claim as my invention, and desire to secure by Letters Patent,is-

'lhe bands O B, with a curved edge, c, and a beveled edge, a, incombination with the hub A, having middle projection d, the beveled edgea pressing against the projection, and the curved edge c pressed intothe wood, substantially as described, and for the purpose set forth.
